thinking about the doom domain spells as currently listed. On one hand they are all fairly innocous from a mechanics standpoint as they are cleric spells of the same level. On a flavor standpoint several fall down I think.
1 Doom
Well, thats pretty striaghtforward, can't really argue.
2 Darkness
Not so sure about this one, though darkness has an evil flavor, there's nothing super doom-y about it. Possible replacements could include Cause Fear and Hideous Laughter or maybe death knell. Going outside cleric spells, chill touch would work too.
3 Bestow Curse
Again, no argument.
4 Control Water
Can't figure this one at all, while it could have specific applications that might fit, so would almost any spell. Poison might be better, and contagion or enervation would be a great flavor fit.
5 Unhallow
Not perfection, but not bad. Slay living, or symbol of pain are more doomish IMHO.
6 Animate Objects
I don't think this one fits, and its also the 6th level domain spell for the chaos domain (one of the other two this cleric would have). Its fine for more than one domain to have the same spell, but since this domains only placement currently is in a diety with chaos, and it isn't a perfect fit, I'd consider other options. Mass inflict moderate wounds, maybe? Harm? Nightmare has possibilities, and eyebite has a curse/hex feeling.
7 Control Weather
not great, but I can see it, especially when dooming entire towns. Symbol of weakness also has a curse sort of feel.
8 Earthquake
same logic as above and an even better flavor. Maybe symbol of insanity to continue the curse/hex motif.
9 Soul Bind
I'm torn between this and Storm of Vengance, which is a spell of doom if ever I saw one...
I might suggest a complete alternate list later, but I thought I'd start with a more open ended critique.
